ConnectingYourVoIPATA
1. Poweroffyournetworkdevices,includingyourmodem
andPC.
2. ConnectoneendofanRJ‐11phonecabletothePhone
Adapter’sPHONE1port.Connecttheotherendtoyour
analogtelephoneorfaxmachineasshownbelow:
3. ConnectoneendofanEthernetnetworkcabletotheLAN
portoftheATA.ConnecttheotherendtotheEthernet
portofyourPC.
4. ConnectoneendofadifferentEthernetnetworkcableto

UpgradingYourFirmware
IMPORTANT:Beforeyouperformtheupgrade,makenoteof
anyaccountandserversettings,plusany
otheruniqueconfigurationsyouhavesetup
onyourdevice.
1. FromyourInternetbrowser,entertheWANIPaddress
ofthedevicetobringuptheWebConfigurationLogin
page.
IMPORTANT:MakesurethatthePCbeingusedfor
upgradingisnotdirectlyconnectedtotheLAN
portofthedevicepriortoupgrading.Performing
thefirmwareupgradeprocedureinthismanner
mayresultindevicefailure.
2. EnterthelogininformationtoentertheWeb
ConfigurationManager.
(Uponlogin,youshouldbedirectedtotheDiagnostic
page.)
3. ClickontheATAConfigtab,andthenclickonthe
“FirmwareUpgrade”link.
4. FromtheFirmwareUpgradepage,selectthe“Browse…”
buttonandselectthefirmwarefilefromyourlocalPC
directory.
5. Oncethefilehasbeenselectedandthedirectorylocation
isvisibleintheATAFirmwareUpgradeFile:lineentry
box,selecttheUpdatebutton.
(Apop‐upwindowshouldappearwithawarningtonot
disruptthepowerconnectionduringtheupgrade
procedure.)
6. StarttheupgradeprocedurebyclickingOK.
Initially,thescreengoesblank.Youwillthenseean
upgradestatusindicator,whichnotescompletion
progressoftheupgrade(i.e.,67%done).
7. Oncetheupgradecompletes,anewpop‐upwindowwill
informyouthatthedevicewillautomaticallyreboot.
ClickOK.
(Thebrowserwindowshouldcloseonitsownunlessthe
browserwindowhasotherpagetabsopenedinthat
window,suchaswithIE7orFirefoxbrowsers.)
8. Waitabout5minutesforthedevicetocompletethe
reboot.Youcanverifythisbycheckingtoseethatthe
WANlightontheboxstartstoflicker(indicatingnetwork
activity).
9. Afterverifyingthatthedevicehasrebooted,holddown
theredRESETbuttononthebackofthedevice(in
betweenthePHONE2portandthepowerslot).

Holdthisbuttondownforabout7‐10secondsuntilyou
seealltheLEDlightsturnoffexceptforthePOWERlight.
(Thisisnecessaryinordertoclearthecachememory
uponupgrading.Afterthedevicereboots,youwillneed
tore‐enteryourdeviceconfiguration.)

tothedevice’sLANport).Therefore,itisimportantthatyou
considerthenumberoftotalphonelinesyouwillbeattachingto
eachCRA‐200deviceinadditiontothetwolinesthatarealready
available.Inthesampleconfigurationshownbelow,whereyou
haveoneCRA‐200boxwithVPNenabledandtwoadditional
Internetphonedevicesforatotalof4phonelines,a128Kbps
Internetconnectionwillallowfornomorethan4simultaneous
phonecallsatagiventimewhenusingcodecG.729/Latency

Forexample,innetworkswith128kDSL,atotalofnomorethan
7simultaneouscallsarerecommendedwithaG.72390mscodec
configurationandVPNenabled.
NOTE:TheDSLspeedsinthetableaboverefertotheMinimum
UploadandDownloadtransferrate.Pleasebeawarethat
yourinternetbandwidthmayfluctuatedependingon
yourprovider’savailability.Resultsmayvarydepending
onfluctuationsofbandwidthavailability.Adecreasein
availablebandwidthwilldirectlyrelatetoadecrease
intotalnumberofallowablecallsandpossiblycall
qualitydependingonbandwidthoverutilization.

IMPORTANT:Thesefiguresassumethatthebandwidthis
dedicatedsolelyforthesevoicecallsandthat
thebroadbandserviceproviderhascommitted
thisbandwidthtotheinstallation.Theuseof
otherInternetservicesmayadverselyaffectthe
amountofallowablesimultaneouscallsalong
withcallquality.
.
CodecLatencyConfiguration:ThissettingontheSIP
Configurationpagedeterminesthevoicesamplesperpacket.
Thenumberofvoicesamplesperpacketisanotherfactorin
determiningthebandwidthutilizedanddelayofaVoIPcall.The
CODECdefinesthesizeofthesample(G.711andG.729havea
samplesizeof10msandG.723hasasamplesizeof30ms),but
thetotalnumberofsamplesplacedinapacketaffectshowmany
packetsaresentpersecond.Whenyouincreasethevoice
payloadsize,thebandwidthutilizedisreducedandtheoverall
delayincreases.Increasingthesesettings(forexample‐from
30msto90msforG.723)canreducebandwidthutilization,but
inturnitmayaffectvoicequalitydependingonthequalityand
stabilityofyourconnection.Forexample,ifyoudroponepacket
duetoconnectivityissues,asettingofG.723/30mswillloseone
voicesamplewhereasettingofG.723/90mswilllose3voice
samples.
